A BORD DE L'USS HW BUSH (Etats-Unis), 10 juil 2013 marine-oceans.com  (AFP)

 

Le X-47B, un prototype de drone furtif, a apponté sur le porte-avions américain USS George HW Bush mercredi, une première ouvrant un nouveau chapitre dans l'histoire de l'aéronavale, a annoncé l'US Navy.

 

L'appareil, contrôlé à distance mais plus autonome que les drones actuels comme le Reaper ou le Predator, avait décollé quelques dizaines de minutes auparavant de la base aéronavale de Patuxent River, dans le Maryland (est), pour rejoindre le porte-avions croisant au large des côtes de Virginie (est).

 

Le X-47B "opère de façon autonome lors de son vol et lors de l'approche du navire mais l'officier d'appontage a un contrôle numérique direct grâce à un bouton" d'interruption en cas de problème, a expliqué le capitaine de vaisseau Jaime Engdahl, responsable du programme.

 

Le démonstrateur, destiné à développer les technologies pour les futurs drones de l'US Navy, avait déjà été catapulté du pont du George Bush le 14 mai.

 

Le X-47B, qui n'a pas d'empennage arrière, est doté d'un moteur à réaction, et a une forme dite en "aile de chauve-souris" pour accroître ses capacités furtives. Il a été conçu depuis 2007 par la firme américaine Northrop Grumman, qui construit également le drone d'observation Global Hawk.

 

L'appareil a une envergure de 19 mètres pour une longueur de 12 mètres. Ce n'est à ce stade qu'un démonstrateur et il faudra de nombreuses années de mise au point avant l'entrée en service opérationnelle de drones dans l'US Navy.

 

Sa portée de 2.100 miles nautiques (3.900 kilomètres) en fait un potentiel bombardier à long rayon d'action.

Old Reliable Beats Out New And Expensive

July 10, 2013: Strategy Page

 

The U.S. Army recently signed a $4 billion deal for another 177 CH-47F transport helicopters. These will cost $22.6 million each and there is an option to add 28 more CH-47Fs to the deal. The first of these new helicopters will arrive in two years. This is a rare multi-year contract, which cuts the price about 16 percent. Congress prefers to allow only deals where the politicians can diddle with contracts on an annual basis. But because this drives up costs, there is pressure to go with the cheaper multi-year contracts and the army managed to get one for its huge CH-47F order.

 

The huge projected cost of developing a new transport helicopter caused the army to decide a decade ago to spend $11.4 billion dollars to refurbish its fleet of existing CH-47 transport helicopters instead. The CH-47 has proved to be a very successful design and none of the proposed replacements was dramatically better than an upgraded CH-47. This upgrade effort will result in a fleet of 513 CH-47F helicopters (including 397 rebuilt CH-47D choppers, 55 new build 47Fs ones plus some special versions.) The CH-47F has been so successful that the army was able to persuade Congress to allow the fleet to be expanded with more new choppers as well.

 

The rebuilt CH-47Ds became CH-47Fs that are good for another twenty years of service. The F model CH-47 has up-to-date digital communications, is easier to maintain, and cheaper to operate. The CH-47F can carry up to 55 troops, and has a maximum range of 426 kilometers. Its max speed is 315 kilometers an hour. Typical missions last no more than 2.5 hours.

 

Three years ago the CH-47F helicopter got its first sustained experience in a combat zone, and performed well. This was a major factor in getting the money to buy more of them. A company of 20 CH-47Fs arrived in Afghanistan during 2009 and soon found themselves often flying eight missions a day, day after day. The CH-47Fs had a 90 percent availability rate. Although the CH-47F has been flying since 2001, and were first delivered to the army in 2009, it takes sustained use in a combat environment to smoke out the last bugs and maintenance problems. In Afghanistan there were some problems with the flat panel displays, but these were quickly worked out. There were several other minor problems, mostly having to do with all the dust in the environment, and the temperature extremes (often below freezing in Winter, and over 45 degrees/113 Fahrenheit in Summer). This was tough on the maintainers and manufacturers' reps initially, but after a year, maintenance problems were no longer an issue. This is important, because in Afghanistan, the CH-47 is a critical form of air transportation, including combat assault.

Since the 1990s the U.S. Army had used UH-60 "Blackhawk" helicopters for combat assault missions, while the larger CH-47 "Chinook" was used just for moving cargo. But the army found that, in the high altitudes of Afghanistan, the more powerful CH-47 was often the only way to go in the thin mountain air. While doing that, the army found that the CH-47 made an excellent assault helicopter. In many ways, it was superior to the UH-60, mainly because the CH-47 carries more troops and moves faster and farther. The CH-47F has even more powerful engines, and is even more valuable for high altitude assaults. It is the best helicopter for use in Afghanistan, having proved able to deal with the dust and high altitude operations better than other transport choppers.

 

The first CH-47s entered service in 1962, able to carry only five tons. Some 750 saw service in Vietnam and 200 were lost in action. During 1982-94, 500 CH-47s were rebuilt to the CH-47D standard. SOCOM operates 31 MH-47Ds and Es, which have additional navigation gear. These are being upgraded to MH-47F standards and the fleet expanded to 61 helicopters. As a result of all this, the CH-47 will end up serving at least 75 years. The original CH-47F upgrade program and new builds will not be completed until 2018. The new contract will extend production into the 2020s.

American fighter pilots (air force, navy and marine) are largely in agreement that, while the F-22 is a superior air-to-air fighter, the new F-35 is a better, if still flawed, all-round combat aircraft. A lot of this has to do with technology. The F-35 is a more recent aircraft, entering service a dozen years later than the F-22. Fighter pilots, who tend to be keen connoisseurs of aviation technology (many being university trained in aviation tech) note that the F-35 is actually using a new generation of tech as much of the F-22 stuff dates back to the 1980s and 1990s. This accounts for some of the tech updates the F-22 has received since it entered service in 2005. But the basic design and composition of the F-35 is a generation ahead of the F-22. As a result the F-35 is cheaper, more effective (in terms of tech), easier to maintain and designed as a fighter-bomber.

 

This last item is important for combat pilots, because they note there has been little air-to-air combat in the last few decades, but smart bombs (especially the GPS variety) have become cheaper, more effective and reliable and that has meant more calls for air support from ground troops. The F-22 is strictly air-to-air and despite heavily publicized efforts to give F-22s ground attack capability, the F-22 has not yet experienced combat. The smart bomb revolution also means that far fewer aircraft are needed and the air force can’t justify sending in the F-22 when there are so many available aircraft that can do the job a lot cheaper. So fighter pilots looking forward to a hot new ride tend to favor the F-35 rather than the F-22.

 

American fighter pilots do see downsides with the F-35. They believe the manufacturer and proponents promised too much and that the F-35 will never be able to deliver. There is a lot of doubt that stealth will work as promised and the shape restrictions on the F-35 (to make stealth possible) limit what the F-35 can do.

 

There are some attractive aspects of the F-35, especially because it comes in three distinct flavors. The vertical take-off F-35B is a 27 ton aircraft that can carry six tons of weapons and will enter service in two or three years. In vertical takeoff mode the F-35B has a range of 800 kilometers. The U.S. Air Force will get its 31 ton F-35A in 2016 or 2017. This is the cheapest version, costing about $154 million each. The U.S. Navy version (the F-35C) will arrive in late 2019 and cost about $200 million each (same as the F-35B). This version has a stronger landing gear to handle carrier landings and components that are more resistant to corrosion from constant exposure to salt water.

 

The F-35 has been delayed many times in the last decade and there is growing talk of cancellation. Orders have already been cut and the manufacturer is under a lot of pressure to get this new stealth aircraft into service. It’s still being debated how many F-35s will actually be produced. The U.S. Air Force assumes 3,162, but the Department of Defense is not so sure that many will eventually be built. Worst case, there will be more than ten times as many F-35s as F-22s. Most (about 60 percent) of the F-35s built will be used by foreign nations.

Last year the 187th, and last, F-22 fighter was completed. This last aircraft was sent to a squadron in Alaska which lost one in an accident two years ago. The manufacturer is not going to scrap or sell off the tools and equipment used to produce the F-22, but will store the stuff for a while in the hope that production may resume eventually.

 

That is unlikely as Congress passed a law forbidding the export of the F-22 fighter. Three nations (Australia, Japan, and Israel) sought to buy some. Efforts to change the law have failed. At one time there was a similar prohibition to the export of the F-16 and that law was changed. One reason for the law was the fear that F-22 technical and operational secrets would fall into the hands of a hostile power that would then build more than 200 of them.

 

The F-22 has performance that is far superior to that of any other aircraft in service, which is why several foreign air forces would like some. The combination of speed, advanced electronics, and stealth technology has created such a decisive advantage that F-22s are often matched up against as many as six F-15s to ensure their pilots face a challenge during training. So why is the F-35, with somewhat lower performance, getting all the export orders?

 

The first reason is price. The F-22 costs up to $200 million each (without even counting the huge R&D costs). The F-35 costs up to half as much (although that edge is eroding). This is one reason the U.S. is pushing exports of the F-35. This is why many more F-16s were exported, compared to the F-15. In any event, the F-35 will outclass a Rafale, F-15E, or Eurofighter, but not the F-22. The U.S. Air Force intended the F-22 to be part of a high-end/low-end mix with the F-35, much like the F-15 and F-16 were the combination in the 1990s, only the F-22/F-35 combination will be much harder to detect and defend against.

 

The U.S. Air Force saw export sales as a way to keep the F-22 production line active, giving it more time to persuade Congress to allow more to be built for the U.S. That did not work. Despite the high cost of the F-22, Russia is developing the similar T-50, and China the similar J-20. But neither of these aircraft is as capable, or as expensive, as the F-22. Neither of these aircraft is in service. The F-22 began development in the late 1980s, first flew in 1997, and entered service in 2005. The F-22 is expected to remain in service for at least 30 years. And for much of that time the F-22 will be the best, if also the least numerous, jet fighter on the planet. During that time many American fighter pilots believe the stealth advantage will be lost due to new technology. China, Russia and the Europeans will continue developing new combat aircraft designs and the appearance of unmanned fighters would change the situation most dramatically of all.

What Next for Army Force Structure? (excerpt)

July 9, 2013 Source: Center for Strategic and International Studies

Two weeks ago, Army Chief of Staff General Ray Odierno announced significant Army force structure reductions. The impending reorganization helps meet an Army obligation and an Army desire. First, the obligation—it allows the Army to satisfy the fiscal demands required by 2011’s Budget Control Act (BCA). Second, the desire—as the Army eliminates brigade headquarters from its structure to meet budget requirements, it can at the same time increase the fighting potential of its brigade combat teams (BCTs). Specifically, the elimination of BCT headquarters frees up an additional maneuver battalion for each of the Army’s infantry and armored BCTs.

The reduction and reorganization of Army forces is not insignificant. As in the case of rebalancing all U.S. forces toward the Asia-Pacific region, Army force reductions are a visible acknowledgment that the Department of Defense (DoD) is entering a new postwar era. It roughly returns active Army force structure to its pre-9/11 configuration, leaving 33 deployable BCTs in the inventory, after having achieved a wartime high of 45 BCTs. There are clearly important, unanswered questions on the table with respect to the Army.

Q1: How should we look at the postwar Army and its contributions to joint operations?

A1: The U.S. Army remains the nation’s principal ground force. It makes two important contingency contributions to joint operations. First, Army forces—active and reserve—provide U.S. decision-makers with the capability for sustained ground operations abroad and potentially in U.S. homeland security contingencies. In reality, Army forces—often reinforced by the U.S. Marine Corps—are tangible demonstrations of American resolve. To paraphrase a senior Marine Corps officer interviewed during the course of a recent CSIS study, when the U.S. Army arrives on scene, it is an unmistakable indication that America means business.

Indeed, the United States’ continued ability to project large numbers of ground forces overseas for sustained operations is a key metric of its remaining the world’s dominant military power. Second and often less appreciated, Army enabling capabilities—logistics, communications, intelligence, engineers, air and missile defense, etc.—“set” foreign theaters and support deployed forces from the other services and foreign partners. This latter function provides a solid backbone for sustained military campaigns of all types under a variety of circumstances. (end of excerpt)

X-47B lands aboard USS George H.W. Bush (CVN 77) July 10 (U.S. Navy photo)

10.07.2013 Helen Chachaty - journal-aviation.com

 

C'est une nouvelle étape capitale qui a été franchie : Le démonstrateur de drone de combat X-47B de Northrop Grumman a effectué avec succès son premier appontage ce 10 juillet. Le drone a décollé de la BAN de Patuxent River, effectuant sa manœuvre d’appontage à bord du plus récent porte-avions de la classe Nimitz, l'USS George H.W. Bush de l’US Navy (CVN-77).

 

C’est un nouveau succès pour le programme UCAS-D de l’US Navy, qui cherche ainsi à étudier et à tester les capacités d’un drone à partir d’une plateforme maritime. Les deux démonstrateurs technologiques X-47B qui sont actuellement utilisés pour les essais n’ont pas vocation à être produits en série et déployés en opérations, mais ils sont néanmoins cruciaux pour les études de R&D et de R&T dans le domaine des appareils non pilotés.

 

Le programme « opérationnel » de l’US Navy est quant à lui nommé UCLASS (Unmanned carrier-launched airborne surveillance and strike system). Une RFI (request for information) a été dévoilée il y a trois ans, l’appel d’offre devrait lui être annoncé prochainement. Il s’agit pour l’US Navy de se doter de capacités ISR ainsi que de capacités de frappe pour équiper ses porte-avions à l’horizon 2018. Lockheed Martin, Boeing, General Atomics et bien sûr Northrop Grumman sont les quatre industriels attendus sur ce créneau.

Un drone US s'est crashé le 9 avril dans le nord du Mali selon le NYT

10.07.2013 par P. CHAPLEAU Lignes de Défense

 

Lu dans le New York Times du 10 juillet:

 

Un des drones US basés à Niamey  (probablement un Reaper) a été perdu lors d'une mission dans le nord du Mali, le 9 avril. Le drone effectuait une mission au profit des forces de l'ops Serval.

 

L'extrait:

"The American missions have not been without incident. On April 9, one of the drones crashed in a remote part of northern Mali, presumably because of a mechanical failure. “It was a total loss,” one Air Force officer said of the wreckage."

Irrécupérable, le Reaper. Le NYT ne dit pas si l'engin a été remplacé.

7/10/2013 1:45:00 PM From Secretary of the Navy Public Affairs Story Number: NNS130710-06

 

USS GEORGE H. W. BUSH, at sea (NNS) -- The X-47B Unmanned Combat Air System (UCAS) demonstrator completed its first-ever carrier-based arrested landing on board USS George H.W. Bush (CVN 77) off the coast of Virginia July 10.

 

"By evolving and integrating new technology like the X-47B and the unmanned aircraft to follow, carriers will remain relevant throughout their 50-year lifespan," said Secretary of the Navy Ray Mabus.

 

Today's demonstration was the first time a tailless, unmanned autonomous aircraft landed on a modern aircraft carrier.

 

This test marks an historic event for naval aviation that Navy leaders believe will impact the way the Navy integrates manned and unmanned aircraft on the carrier flight deck in the future.

 

In May 2013, the X-47B successfully completed underway carrier deck operations aboard USS George H. W. Bush to include a first-ever catapult launch and nine touch-and-gos.

 

"We have certainly come a long way in the 102 years since Eugene Ely made the first arrested landing aboard an aircraft carrier. Naval aviators have always been at the forefront of operational and tactical innovation, and today was no exception," said Mabus. "People make unmanned aviation possible and it is people who will provide the fresh thinking and new ideas so crucial to successes like the X-47B program and the unmanned aircraft of the future."

 

The Navy will continue to update this story as more information from today's demonstration is made available.

Northrop Grumman Supports Propulsion System Rocket Engine Test

Jul 10, 2013 (SPX)

 

Herndon VA - Northrop Grumman recently supported the successful test of the Minuteman III Propulsion System Rocket Engine (PSRE) at NASA's White Sands Testing Facility in Las Cruces, N.M.

 

The PSRE is the liquid post-boost upper stage of the Minuteman III intercontinental ballistic missile (ICBM). This was a designated product quality assurance (PQA) test, which is a full mission duty ground static test conducted in NASA's altitude test cell.

 

The PQA test is performed to verify the quality of the PSRE after it is refurbished by the PSRE life-extension program (LEP).

 

This test represents the last of seven PQA static tests for the PSRE LEP program.

 

"The entire ICBM team, including our Aerojet and Boeing teammates and the Air Force, celebrate the success of this program as it comes to an end with this final accomplishment," said Tony Spehar, Northrop Grumman vice president and program manager for the ICBM Prime Integration Contract.

 

"These PSRE tests have ensured the reliability of the nation's deployed Minuteman fleet."

 

The PSRE LEP program, initiated in 2000, is managed under a joint partnership between Northrop Grumman and the U.S. Air Force.

 

The program is responsible for refurbishing the entire Minuteman III fleet of PSREs and extending its service life through 2030. Upon completion of the program last month, 558 PSREs will have been delivered to the Air Force.

The US Army is implementing a new preventative maintenance concept, called condition-based maintenance plus (CBM+), in an effort to enhance efficiencies and reliability of its tactical communications network systems.

 

Implementation by the product manager for Warfighter Information Network-Tactical Increment 3 (PdM WIN-T Increment 3) follows a recent study, which confirmed the concept's ability to enhance system performance, while delivering a six-to-one return on investment.

 

WIN-T Increment 3 product manager lieutenant colonel Ward Roberts said the approach was designed to increase equipment performance, while simultaneously decreasing maintenance and support footprints.

 

"Considering that the bulk of a programme's costs are in logistics and sustainment, we see CBM+ as an opportunity to increase efficiencies, not only for our program, but for other army programmes as well," Roberts added.

 

Already pursued by the army for its aviation fleet, CBM+ strategy is focused on improving diagnostics and anticipatory maintenance, compared with the legacy reactive maintenance, and is also capable of offering error codes to highlight an impending problem to soldiers, preventing a system failure.

 

The existing network management software (NMS) used by WIN-T Increment 1 and WIN-T Increment 2, alerts soldiers only after equipment failure.

"Considering that the bulk of a programme's costs are in logistics and sustainment, we see CBM+ as an opportunity to increase efficiencies, not only for our program, but for other army programmes as well."

 

In addition, CBM+ can order required parts on forward operating bases (FOBs) and send them back to the unit, as opposed to common practice, which involves equipment swapped with spares if the failure cause is unclear, and subsequent transfer to depot, often resulting in unncecessary wastage, costs and time.

 

The concept also facilitates work on an as-needed basis by providing alerts when the equipment reaches a certain threshold of operation set on the system's sensors, generating significant maintenance time and cost savings for the army.

 

Implementation is scheduled to be carried out in increments called spirals, with spiral 1 focused on WIN-T Increment 3's advanced network operations capabilities, followed by its scheduled developmental testing in 2015 and limited user testing in 2016.

 

Spiral 1 will assist signal officers in network management, while Spiral 2 will focus on external interfaces to the army logistics systems.

Mikros Systems has received a contract from the US Navy to provide new condition-based maintenance capabilities for radars and electronic systems installed onboard littoral combat ships (LCS).

 

Under the $2.8m contract, Mikros will extend adaptive diagnostic electronic portable test-set (ADEPT) systems capabilities to the ADEPT distance support sensor suite (ADSSS) to the US Navy.

 

Mikros chief technology officer (CTO) Henry Silcock said the new project would complete the initial LCS's ADEPT engineering effort, which started in 2012.

 

"The ADEPT distance support sensor suite on LCS will provide a complete and integrated data collection, diagnostics, prognostics, and data transfer solution for four key combat systems on both variants of the LCS," Silcock said.

 

Mikros president Tom Meaney added: "Once this project is complete, we expect to begin installing ADSSS on all LCS ships."

 

The ADEPT intelligent, automated, programmable electronic test tool will enable technical personnel to maintain, align, calibrate, and error diagnosis of radar and other complex electronic systems.

 

In addition to helping in detection and troubleshooting of error and out-of-alignment conditions, the ADEPT improves system readiness and operational performance, as well as reduces equipment downtime and lifecycle support costs through enhanced automation, distance support and interactive training.

 

More than 100 ADEPT systems have been delivered over the past three years to the US Navy for installation on to Aegis-equipped vessels to reduce shipboard maintenance and deliver new distance support solutions.

 

The US Navy's LCS vessels have been designed to support a range of missions such as defeat asymmetric anti-access threats including mines, quiet diesel submarines and fast surface craft in near-shore environments.

Syrie: le Congrès US contre la livraison d’armes américaines aux rebelles

MOSCOU, 10 juillet - RIA Novosti

 

L'opposition syrienne ne recevra probablement pas d’aide militaire américaine dans un avenir proche. Du moins officiellement - car les rebelles reçoivent déjà depuis longtemps des armes de l'Otan d'une manière officieuse, écrit le quotidien Rossiïskaïa gazeta du 10 juillet 2013.

 

Les comités pour le renseignement des deux chambres du Congrès américain se sont une nouvelle fois opposés au président Barack Obama en décidant de bloquer son initiative d’aide militaire directe à l'opposition syrienne. Leur argument? Ils n'ont pas envie de dépenser de l’argent pour ça. Leur décision s'explique par une crainte - tout à fait justifiée - de l'avenir de cet armement : ce dernier pourrait facilement tomber entre les mains des terroristes, y compris des combattants liés à Al-Qaïda. Moscou a déjà plusieurs fois prévenu Washington d'une telle éventualité.

 

Les parlementaires ont pris leur décision en fonction d’informations secrètes. Ces informations étaient-elle donc inaccessibles à Barack Obama quand il a annoncé sa volonté sincère d'aider les séparatistes à renverser le régime de Bachar al-Assad?

 

Les experts américains soulignent que ces limitations suffisent pour empêcher les livraisons d'armes en Syrie. Mais il semble évident qu’en jugeant ainsi la situation ils prennent leurs désirs pour des réalités: nul n'ignore l'existence des "caisses noires" de la CIA et d'autres services américains qui ont assez d'argent pour financer plus d'une guerre régionale.

Echec d’interception de missile lors d’un essai aux États-Unis

09.07.2013 Helen Chachaty - journal-aviation.com

 

Le département américain de la Défense a révélé qu’un essai d’interception de missile balistique mené entre autres par la Missile Defence Agency avait échoué le 5 juillet dernier, pour une raison encore inconnue. Le but de la manœuvre était d’intercepter à partir de la base de Vandenberg, en Californie, un missile balistique de longue portée lancé par l’US Army d’une base des Îles Marshall dans le Pacifique. Une enquête a été lancée pour déterminer les causes de cet échec.

 

Selon le Los Angeles Times, l’essai aurait coûté 214 millions de dollars et le dernier succès serait daté de 2008. Les essais d’interception auraient été stoppés au début de l’année 2011, suite à deux échecs répétés en 2010 avec deux nouveaux intercepteurs. Le Los Angeles Times précise que le système de défense sol-air est fabriqué par Boeing et que le « kill vehicle » provient de Raytheon.

Artemis Trident 2013 : coup d'envoi d'une coopération future

9/07/2013 Marine nationale

 

À l’occasion du déploiement actuel du groupe de guerre des mines dans le golfe arabo-persique, l’état-major de conduite des opérations de guerre des mines, les chasseurs de mines Sagittaireet Pégase, ainsi qu’un détachement de douze plongeurs démineurs ont participé à l’entraînement tripartite Artémis Trident 2013. Cet exercice anglo-franco-américain s’est déroulé au large des côtes bahreinies, du 18 au 27 juin 2013.

 

Le principal enjeu était de tester, voire d’augmenter, interopérabilité de ces trois marines dans le domaine de la guerre des mines. Outre les moyens français, deux aéronefs (NH 53), deux chasseurs de mines et un détachement de plongeurs démineurs américains, ainsi que quatre chasseurs de mines anglais ont pris part à l’entraînement.

 

Les États-Unis sont en effet une des deux seules nations au monde (avec le Japon) à opérer les trois composantes de guerre des mines : air (dragage et chasse par hélicoptères), surface (chasseurs de mines) et sous marin (mise en oeuvre d’AUV  1). Fruit d’un travail de longue haleine, la concrétisation d’une telle coopération permet de construire des bases solides pour la conduite d’opérations futures de guerre des mines communes dans le golfe arabo-persique et semble vitale pour garantir les accès maritimes des points d’intérêts nationaux.

 

Ces neufs jours d’entraînement ont également permis d’échanger sur les méthodes de travail et procédures de chaque nation.

Artemis Trident 2013 : coup d'envoi d'une coopération future

Le capitaine de vaisseau Benon a commandé le groupe de guerre des mines français ainsi que la force tripartite constituée pour Artémis Trident. Rapide retour d’expérience (Retex).

 

« Quel bilan pouvez-vous dresser d’Artemis Trident 2013 ?

 

- Ça a été une coopération opérationnelle étroite, dans cette région du monde, avec nos alliés naturels que sont les États-Unis et le Royaume-Uni a beaucoup de sens. D’une part, nos intérêts stratégiques sont largement partagés et d’autre part, il est évident qu’une opération de guerre des mines, dans le golfe arabo-persique comme ailleurs, ne peut être envisagée qu’en coalition.

 

Par ailleurs, pour les forces de guerre des mines françaises, les déploiements périodiques réalisés dans cette région du monde correspondent à un besoin de diversification de nos zones habituelles de travail.

 

Ils constituent un complément indispensable aux opérations contingentes conduites très régulièrement depuis trente ans sur les côtes françaises et européennes en général, que ce soit en Atlantique ou en Méditerranée. Dans le golfe arabo persique, l’environnement marin est exigeant (il fait très chaud et la température de l’eau oscille entre 28°C et 33 °C), l’environnement opérationnel également. C’est au travers d’entraînement comme Artemis Trident que nous améliorons nos propres modes d’action mais surtout notre capacité à travailler mieux et plus vite en coalition ».

REGARDS CROISÉS

 

Le CC Roussel est le commandant le chasseur de mines  Pégase. Sa réaction

 

« L’équipage du Pégase a relevé le défi Artemis Trident avec enthousiasme, impatient d’éprouver le savoir-faire français, acquis davantage sur les fonds chaotiques de la mer d’Iroise que sur les fonds sablonneux du golfe. Depuis les principes généraux jusqu’aux procédures les plus techniques, chaque action, menée en parallèle par chacun des chasseurs de mines engagés, a été évaluée et comparée avec précision. Par ailleurs, les riches échanges entre participants ont activement participé à la définition d’un socle de connaissances techniques communes, premier pas vers l’intégration en cas d’engagement multinational. ».

What does the future hold for JIEDDO? Three options on the table...

07/08/2013  Andrew Elwell - defenceiq.com

 

One of the big questions relating to the reorganisation of the Armed Forces following the withdrawal from Afghanistan relates to the future of Joint Improvised Explosive Device Defeat Organization (JIEDDO). Will it still be an operational necessity or is the argument for its continued economic outlay too fragile?

 

The unit was formed in 2006 after a spate of deadly incidents involving the roadside bombs forced the US government to act. JIEDDO has been central to informing opinion on IEDs for a decade but senior US defence officials are now discussing its future. There are three options being considered: maintain JIEDDO’s capabilities but split its duties between the military forces; scale down its operations and house it within the Office of the Secretary of Defense (OSD); or shut it down.

 

Colonel Gareth Bex, Head of Army EOD & Search at the UK MoD, is a man who would have an opinion on JIEDDO’s future effectiveness. He spoke at the Counter-IED conference in London last month and insisted that “the genie is out of the bottle [for insurgents and their effective use of IEDs], and there’s no way it’s going back in.”

 

Col Bex went on to say that the UK failed to continue the investment it made in this area after Northern Ireland and lost the mainstay of its C-IED capabilities as a result. When protection against IEDs and mine blasts wasn't top of the agenda anymore it was easy for that investment to be directed into other avenues. Bex wonders if the same may happen again post-Afghanistan, especially considering the current economic climate. But it mustn't. The lessons learned from Afghanistan must not be allowed to be forgotten like they were after Northern Ireland - the only way to do that is maintain investment in the area and continue to take the threat seriously.

 

“IEDs are certainly an enduring global threat,” said Col Bex.

 

With that in mind, how can the US justify the elimination of JIEDDO? It would be imprudent, and short-sighted.

 

While breaking up the organisation and spreading it out through the military services – a process known as disaggregation – is a viable option, the best, and perhaps most likely option for the JIEDDO may be to roll it into the OSD.

 

JIEDDO has spent in the region of $20 billion since 2006, including the largest and most ambitious UOR programme ever for the design and acquisition of the Mine Resistant Ambush Protected (MRAP) family of vehicles.

09/07/2013 par Nicolas Laffont – 45eNord.ca

 

Dans le cadre d’un plan à long terme du Département américain de la Défense, l’US Army a produit une vidéo pour attirer des soumissionnaires et les inciter à repousser les limites de la technologie dans le développement d’un hélicoptère de nouvelle génération et de ses flottes utilisant les rotors basculants.

 

«J’ai besoin de visionnaires de l’aviation», lance ainsi Bill Lewis, directeur de la Direction du développement de l’aviation de l’armée de terre, dans la vidéo de 7 minutes. «Le seul facteur limitant est votre imagination.»

 

En réponse à la vidéo, la société Hurst, basée au Texas (et faisant partie de Bell), a produit sa propre vidéo mettant en vedette des acteurs qui défoncent rapidement des portes et «accomplissent leur mission» avec l’aide du V-280 Valor, la version du rotor basculant de Bell pour un avion conjoint multi-rôle.

 

La production de Bell, mettant en valeur le Valor, commence avec deux enfants jetant leurs cartables pour voir la vidéo. «Chouette appareil du futur» , dit un gamin. «J’ai bien hâte de voler avec ce bad boy.»

Dans les deux vidéos, le thème semble être le pouvoir de transformation de la technologie pour façonner les futures guerres en des jeux de clic de souris dans lesquels les gentils ne meurent jamais, et avec encore moins de sang.

 

Bell Helicopter, AVX Aircraft Co. et une coentreprise de Boeing Co. et Sikorsky Aircraft Corp. ont d’ores et déjà soumis leur concept à l’armée américaine d’un Démonstrateur de technologie conjoint multi-rôle.

 

L’armée envisage de prendre une décision initiale sur le démonstrateur en septembre, avec un prototype volant prêt pour 2017.

 

Les propositions de Bell, AVX et Boeing-Sikorsky pour le Démonstrateur de technologie conjoint multi-rôle ne sont qu’un premier pas dans le plan global du Pentagone annoncé en 2011 d’avoir l’armée prendre l’initiative des prototypes pour remplacer la flotte vieillissante de plus de 4000 hélicoptères dans toutes les armes.

 

«L’avion de nouvelle génération devra être un ensemble beaucoup moins coûteux à exploiter que la flotte actuelle» et être prêt à entrer sur la ligne de front dans les années 2020, a déclaré le major-général William Crosby, responsable du programme de l’aviation pour l’armée.

 

«Même avec tout l’excellent travail que nous faisons pour la mise à niveau et le soutien de la flotte actuelle, il est maintenant temps d’investir dans la science et la technologie nécessaires pour développer la future flotte», a dit William Crosby.

 

«Nous avons encore des plates-formes élévatrices verticales de troisième génération conçues pendant la période de la guerre du Vietnam, il y a près de 50 ans», a-t-il dit. «Notre flotte actuelle ne durera pas éternellement et il y a des limites à notre capacité d’améliorer les modèles actuels pour répondre aux besoins futurs.»

Pentagon Releases First Annual Acquisition Report

July 8, 2013 Source: U.S Department of Defense



WASHINGTON --- A recently completed defense acquisition program report, which is now before Congress, is part of a data-driven effort to find out what’s working best in equipping the nation’s military and to fix what isn’t, the Pentagon’s undersecretary of acquisition, technology and logistics said in an interview with American Forces Press Service.

Frank Kendall said the report, the first in what’s expected to become a series of annual reviews, evaluated major programs across the department. The study is a step toward mastering the mountain of data military acquisition generates.

“Even our best performers have room for improvement,” the undersecretary said. “Figuring out what to do to improve, I think, is the next question.”

Kendall often references the large, engraved wooden sign outside his office door bearing a quote from the late American statistician and professor W. Edwards Deming: “In God we trust; all others must bring data.”

“I’m a firm believer that improvements to policies and processes must be driven by data and objective analysis rather than conjecture and opinion,” Kendall said, adding the report “begins to share [that] kind of objective analysis.”

Kendall said an institutional-level view of defense acquisition -- a field that includes research and development, testing and evaluation, fielding and maintenance of virtually all U.S. military equipment -- is important because “our processes tend to come from our institutional cultures and norms.”

Acquisition underlies all military operations, he noted, adding, “If you’re serving out there and you’re waiting for the next generation of whatever piece of equipment, this is the system that’s producing that for you. … There are a lot of very hard-working people in government and industry trying to do that.”

The point of the report, Kendall said, “is to help us all figure out ways to do a better job with [acquisition]” and ultimately to ensure more and better products.

The report doesn’t make judgments or excuses, he noted.

“I want each institution to look at how well they are performing compared to others and ask themselves how they learn from one another to improve performance,” he added.

Kendall said the report shows that, in some measures, program and organizational performance across the department has improved, but more progress is needed.

“Very recent data show statistically significant improvement, but only time and further analysis will tell if these trends continue into the future,” he said. “For example, comparing the last two decades, the Army and Air Force have reduced total cost growth on contracts, and the Army has reduced contract costs-over-target. The Air Force also has lowered contract schedule growth.”

Kendall said despite such trends, “The magnitude of absolute performance issues leaves considerable room for additional improvement. Due to the nature of pushing the state-of-the-art in weapon systems, we will never have zero cost and schedule growth. But, we can certainly do better and have recent indications that this is possible.”

One major finding from the report is that “a lot of the things we thought were important may not be as important as we believed,” he said. “Fixed-price versus cost-plus contracting, for example.”

Fixed-price contracts are let at a set price for the work, while cost-plus contracts reimburse the contractor’s expenses and also add other funds, which can include award, incentive and performance fees.

Statistics for the two kinds of contracts were more similar than he expected, Kendall said. He added he’s never thought fixed-price contracts were “a panacea,” and while conventional wisdom is that fixed pricing solves a lot of problems, “I don’t think that’s the case, and the data shows that.”

Unsurprisingly, the review found that undefinitized contracts show the highest cost growth, the undersecretary said. The department can use these types of contracts to meet urgent needs, as they authorize contractors to begin work before contract terms are set.

“We tend to over-run our development programs … by about 30 percent,” Kendall said. “We tend to over-run our production programs by about 10 percent. So there’s a lot more variability and uncertainty and risk on the development side of the house.”

If the buyer hasn’t defined requirements or projected costs, he said, “You’re going to start a lot of people doing a lot of work that they’re not really ready to do, and that leads to huge inefficiencies. … The data shows that very strongly.”

Kendall added that the data also surprised him by showing that “undefinitized contract actions do not generally correlate with total cost growth on early procurement contracts. We found that it is a factor in development, but we were worried that the effect was also statistically measurable in procurement but is, in fact, not.”

Kendall said he wants to do more work on understanding which factors matter and how they correlate, but that all analysis to date points to the importance of good management.

“It wasn’t a surprise to me,” the undersecretary said. “I’ve been emphasizing the professionalism of the acquisition workforce … it’s been a constant theme of mine.”

Any project benefits from better management, Kendall noted. “We could avoid a lot of our disasters, and we could do much better in the margins in all of our programs, the better we are at managing programs and making sound decisions,” he added.

Examining factors in cost growth always leads to “a whole host of additional questions you have to ask,” Kendall said. Future reports will examine more and different defense acquisition data and institutions, both government and industry, he noted.

“It will also expand on the analysis,” he said. “I’m very open to ideas about how we get at understanding what’s really going on in the acquisition system.”

Two key take-aways from the report, Kendall said, are first, that the United States has a decisive strategic edge in its military, which is the best in the world; and second, that “the fact that it may cost us too much and take us too long to get there shouldn’t be neglected, either.”

Kendall said he had expected many of the report’s findings.

“We knew that cost growth has been high and that the recent wars have placed a premium on technical performance and schedule at the expense of cost growth,” he said. “The report reinforces the importance of our Better Buying Power initiative that [Deputy Defense Secretary Ash Carter] and I began in 2010 and I have continued to expand.”

Kendall told reporters during a Pentagon briefing in May that Better Buying Power 2.0 is a step forward in “a very, very complicated business.”

Kendall said Better Buying Power 2.0 covers a wide range of products and services that defense acquisition requires. There were 23 initiatives in Better Buying Power 1.0, 34 in 2.0 and “another 100 things, at least, that we’re working on,” he said during that briefing.

This new report, Kendall said, offers an analytic basis for further action. “For example, the finding that fixed-price contracts are not a ‘magic bullet’ to controlling cost has reinforced my experience that we need to consider and select the most appropriate contract type given the maturity, system type and business strategy for each system,” he said.

The report’s findings should help “reinvigorate cost consciousness in our culture,” Kendall said.

“This is especially important now that we are winding down the wars and have such intense fiscal constraints on the department,” he said. “We all must weigh not just the benefits of a particular capability, but also its benefits given the cost to the taxpayers.”

PMA-290, PMA-201 successfully launch missile during testing evolution

Jul 9, 2013 ASDNews Source : Naval Air Systems Command

 

After approximately six minutes of flight time, one of NAVAIR’s test aircraft successfully launched a Harpoon missile during a live fire event June 24 in California at the Navy’s Point Mugu Sea Test Range and scored a direct hit on a Low Cost Modular Target.

 

Completing only one practice dry run, a P-8A Poseidon from Air Test and Evaluation Squadron (VX) 20 successfully fired a Harpoon AGM-84D Block IC missile from station 10 on the first hot run, which was later confirmed by onsite explosive ordnance disposal personnel.

 

“The successful launch of one of the U.S. Navy's most dependable over-the-horizon all-weather anti-ship missiles, the Harpoon Block IC, from the P-8A is a significant milestone in naval aviation,” said Capt. Carl Chebi, Precision Strike Weapons (PMA-201) program manager.

 

For more than 40 years, the Harpoon weapon system has served the Navy well by offering a low-level and sea-skimming cruise trajectory that supports high survivability and effectiveness. This air-launched variant of the Harpoon 1C is currently integrated on the P-3C.

 

According to Maritime Patrol and Reconnaissance Program Office (PMA-290) Program Manager Capt. Scott Dillon, the significance of this program milestone is that the P-8A was able to launch the Harpoon at a target and achieve a direct hit.

 

“As the Navy’s replacement for the P-3 Orion, the P-8A Poseidon will be performing maritime surveillance missions as needed by the operations tempo and the success of this testing evolution brings us one step closer to Initial Operational Capability [IOC] this fall,” Dillon said. “The test was very successful and the Harpoon directly hitting the target proves the system’s capability and lethality.”

 

The purpose of this test was to validate the weapons hardware and software integration. The weapons integration testing that was achieved last week at Point Mugu was a culmination for all of the lab development and integration as well as developmental testing over the past year to get one step closer to fielding an anti-surface warfare (ASuW) weapon for fleet IOC, said Paul Sheridan, the P-8A assistant program manager for system engineering assigned to PMA-290’s Weapons Systems Integration team.

 

At the completion of this developmental testing, the P-8A will be ready for Harpoon operational testing to support fleet IOC.

 

“This live-fire event was made possible through the efforts of teams across NAVAIR including PMA-290 and PMA-201 here, in China Lake and Corona, Calif.,” said Chebi. “The teams continuously meet the challenges placed before them from test-asset preparations, ground testing, separation tests and the end-to-end live-fire evaluation. PMA-201 will continue to support the P-8A program and provide solutions to meet current requirements as well as the integration of future requirements that will advance the Navy's long-range maritime patrol capability.”

 

Dillon and Sheridan agreed with Chebi that the Harpoon P-8A testing was a collaborative effort between PMA-290 and PMA-201.

NGC Moves New B-2 Satellite Communications Concept to the High Ground

Jul 8, 2013 ASDNews Source : Northrop Grumman

 

    Company Proves New Antenna Can Communicate, Operate With On-Orbit Satellite

 

Northrop Grumman Corporation (NYSE:NOC) has taken another significant step to reduce the risks and costs associated with producing an extremely high frequency (EHF) satellite communications system for the U.S. Air Force's B-2 stealth bomber.

 

In a demonstration conducted May 23, Northrop Grumman proved that a new active electronically scanned array (AESA) antenna it has developed for the B-2 can establish and maintain communications services with an on-orbit Air Force Advanced EHF (AEHF) communications satellite. The demo included the antenna, a Navy Multi-band Terminal and the satellite.

 

Northrop Grumman is the Air Force's prime contractor for the B-2, the flagship of the nation's long range strike arsenal, and one of the world's most survivable aircraft. An EHF satellite communications system would allow the B-2 to send and receive battlefield information significantly faster than its current satellite communications system.

 

"Our demo marks the first time that AESA antenna technology has been used to communicate with the AEHF network," said Byron Chong, Northrop Grumman's B-2 deputy program manager. "We showed that our antenna will consistently produce and maintain the high-gain beam needed to communicate with AEHF satellites."

 

During the test, he added, Northrop Grumman successfully demonstrated extended data rate (XDR) communications between the AESA antenna and the AEHF satellite at EHF frequencies. XDR communications take advantage of the AEHF satellites' most advanced, most secure signaling protocols and communication waveforms.

 

The new antenna is designed to support both tactical and strategic missions. Its innovative "no radome" design allows it to bring new communications capabilities to the B-2 while maintaining the aircraft's major operational characteristics.

 

Earlier this year, Northrop Grumman validated the performance of the new antenna on instrumented test ranges. The tests verified the antenna's performance over its entire transmit and receive frequency band, and over its required range of scan angles.

 

The B-2 is the only long-range, large-payload U.S. aircraft that can penetrate deeply into access-denied airspace, and the only combat-proven stealth platform in the current U.S. inventory. In concert with the Air Force's air superiority fleet, which provides airspace control, and the Air Force's tanker fleet, which enables global mobility, the B-2 can help protect U.S. interests anywhere in the world. It can fly more than 6,000 nautical miles unrefueled and more than 10,000 nautical miles with just one aerial refueling, giving it the ability to reach any point on the globe within hours.
